Mixed feelings: the case of ambivalence

The expression of decision and learning variables in movement patterns related to decision actions

Decisions are not necessarily easy to separate into a planning and an execution phase and the decision-making process can often be reflected in the movement associated with the decision. Here, we used formalized definitions of concepts relevant in decision-making and learning to explore if and how these concepts correlate with decision-related movement paths, both during and after a choice is made. To this end, we let 120 participants (46 males, mean age = 24.5 years) undergo a repeated probabilistic two-choice task with changing probabilities where we used mouse-tracking, a simple non-invasive technique, to study the movements related to decisions. The decisions of the participants were modelled using Bayesian inference which enabled the computation of variables related to decision-making and learning. Analyses of the movement during the decision showed effects of relevant decision variables, such as confidence, on aspects related to, for instance, timing and pausing, range of movement and deviation from the shortest distance. For the movements after a decision there were some effects of relevant learning variables, mainly related to timing and speed. We believe our findings can be of interest for researchers within several fields, spanning from social learning to experimental methods and human-machine/robot interaction.

Movement trajectories as a window into the dynamics of emerging neural representations

The rapid transformation of sensory inputs into meaningful neural representations is critical to adaptive human behaviour. While non-invasive neuroimaging methods are the de-facto method for investigating neural representations, they remain expensive, not widely available, time-consuming, and restrictive. Here we show that movement trajectories can be used to measure emerging neural representations with fine temporal resolution. By combining online computer mouse-tracking and publicly available neuroimaging data via representational similarity analysis (RSA), we show that movement trajectories track the unfolding of stimulus- and category-wise neural representations along key dimensions of the human visual system. We demonstrate that time-resolved representational structures derived from movement trajectories overlap with those derived from M/EEG (albeit delayed) and those derived from fMRI in functionally-relevant brain areas. Our findings highlight the richness of movement trajectories and the power of the RSA framework to reveal and compare their information content, opening new avenues to better understand human perception.

Do uncontrolled processes contribute to evaluative learning? Insights from a new two-US process dissociation procedure and ambivalence measures

The contribution of uncontrolled processes to evaluative learning has been examined in evaluative conditioning procedures by comparing evaluations of conditioned stimuli between tasks or within tasks but between learning instruction conditions. In the present research, we introduced a new procedure that keeps both tasks and instructions constant. In addition, we introduced ambivalence measures to address this uncontrollability question. The new procedure involves forming an impression of conditioned stimuli based on their pairing with one unconditioned stimulus while attending but discarding the influence of another unconditioned stimulus holding the same (congruent trials) versus a different (incongruent trials) valence. When the to-be-used and to-be-discarded unconditioned stimuli share the same (vs. a different) valence, controlled and uncontrolled processes should support the same (vs. opposite) responses. We used this approach in two preregistered experiments (Ntotal = 467) using dichotomous evaluative classifications (Experiments 1 and 2), evaluative ratings, and two measures of attitudinal ambivalence: mouse trajectories and felt ambivalence (Experiment 2). While we failed to find evidence for uncontrolled processes in evaluative classification frequencies separately in Experiments 1 and 2, analyses of aggregated classification frequencies across Experiments 1 and 2 suggested a small contribution of uncontrolled processes. In addition, we found larger felt ambivalence for incongruent than congruent trials. Overall, the present findings are mixed but support the possibility of a contribution of uncontrolled processes to evaluative learning, even when control is applied to a focal stimulus and additional influences come from a to-be-disregarded stimulus.

Measuring feelings about choices and risks: The Berlin Emotional Responses to Risk Instrument (BERRI)

We introduce a brief instrument specifically validated for measuring positive and negative feelings about risks-the Berlin Emotional Responses to Risk Instrument (BERRI). Based on seven studies involving diverse adults from three countries (n = 2120), the BERRI was found to robustly estimate anticipatory affective reactions derived from subjective evaluations of positive (i.e., assured, hopeful, and relieved) and negative emotions (i.e., anxious, afraid, and worried). The brief BERRI outperformed a 14-item assessment, uniquely tracking costs/benefits associated with cancer screening among men and women (Studies 1 and 2). Predictive validity was further documented in paradigmatic risky choice studies wherein options varied over probabilities and severities across six contexts (health, social, financial, technological, ethical, and environmental; Study 3). Studies 4-6, conducted during the Ebola epidemic and COVID-19 pandemic, indicated BERRI responses were sensitive to subtle effects caused by emotion-related framing manipulations presented in different cultures and languages (the United States, Spain, and Poland). Study 7 indicated BERRI responses remained stable for 2 weeks. Although the BERRI can provide an estimate of overall affect, choices were generally better explained by the unique influences of positive and negative affect. Overall, results suggest the novel, brief instrument can be an efficient tool for high-stakes research on decision making and risk communication.

Contexts of Concealment: Initial Validation of Three Disclosure Avoidance Process Measures

The choice to withhold subjective distress reflects a multifactorial decision highly sensitive to context. Unfortunately, existing measures are built on unidimensional models (i.e., concealment-disclosure as a single, bipolar dimension) and operationalize the construct as a stable trait. In this article, we outline the development and initial validation of a self-report inventory that accounts for problem-context and assesses multiple processes central to both the concealment and disclosure of emotional distress. Exploratory analysis of pilot items in Study 1 (male student sample; N = 373) guided subsequent item development and revisions to our conceptual model. In Study 2 (mixed-gender community sample; N = 297), we refined the item-pool based on additional tests of latent scale structure and associations with concurrent criteria. In a final validation sample (Study 3; international community participants; N = 978), confirmatory factor analyses corroborated our hypothesized three-factor model (Privacy Management, Disclosure Desire, and Social Fear) and supported measurement invariance by sex. The three Contexts of Concealment Scales (CCS) were internally consistent and associated in expected directions with external indices of concurrent concealment, disclosure, depression, anxiety, loneliness, experiential avoidance, and self-stigma.

Cross-valence inhibition in forming and retrieving ambivalent attitudes

Many things in life are ambivalent, and it might sometimes be useful or necessary to ignore their positive attributes when judging their negative attributes and vice versa. Cross-valence inhibition may complicate this task, leading people to underestimate the positive and negative attributes of ambivalent stimuli. In three studies (total N = 155), participants learned to associate combined evaluative information (gains and losses) with attributes of unfamiliar objects (size and colour of Chernoff faces). Participants then estimated (Studies 1-3) or experienced and recalled (Study 3) the gains and losses associated with novel ambivalent attribute combinations. As predicted, both in estimation and recall, participants rated gains (losses) to be lower, the higher the losses (gains) associated with the stimulus. The effect occurred only when the two attributes were evaluatively conflicting (Study 2). Cross-valence inhibition might lead to maladaptive behaviour when positive and negative attributes are in fact separable in hedonic experience.

The social tensions felt within: Explaining felt ambivalence about polarized societal debates through perceived opinion discrepancies in the social environment

Within the context of polarized societal debates (e.g. abortion, racism, climate change), scholars often assume that individuals have clear-cut positions, either in favour of or against the debated issue. However, recent work suggests that such debates can also be breeding grounds for felt ambivalence. Moving beyond previous work that mainly focused on ambivalence as internal cognitive conflict, we propose and test a social discrepancy hypothesis, which suggests that the discrepancies ambivalents perceive between and within their own opinion and the opinion of actors in their social network and society (e.g. friends, family, opinion-based groups) positively explain their levels of felt ambivalence. In doing so, we quantitatively extend recent qualitative work by examining whether these social tensions are indeed felt within. To this end, we employed a multi-survey research project (Ns = 184, 181, 187) in the context of different societal debates in the Netherlands. Supporting our hypothesis across different debates, results showed that ambivalents' perceived opinion differences in the social environment explained their felt ambivalence. This suggests that polarized societal debates offer social discrepancies that, for ambivalents at least, can facilitate an internalization of social tensions.

The biased hand. Mouse-tracking metrics to examine the conflict processing in a race-implicit association test

In this study, we adapted a race-Implicit Association Test (race-IAT) to mouse-tracking (MT) technique to identify the more representative target observed MT-metrics and explore the temporal unfolding of the cognitive conflict emerging during the categorisation task. Participants of Western European descent performed a standard keyboard-response race-IAT (RT-race-IAT) and an MT-race-IAT with the same structure. From a behavioural point of view, our sample showed a typical Congruency Effect, thus a pro-White implicit bias, in the RT-race-IAT. In addition, in the MT-race-IAT, the MT-metrics showed a similar Congruency Effect mirroring the higher attraction of the averaged-trajectories towards the incorrect response button in incongruent than congruent trials. Moreover, these MT-metrics were positively associated with RT-race-IAT scores, strengthening the MT approach’s validity in characterising the implicit bias. Furthermore, the distributional analyses showed that mouse trajectories displayed a smooth profile both in congruent and incongruent trials to indicate that the unfolding of the decision process and the raised conflict is guided by dynamical cognitive processing. This latter continuous competition process was studied using a novel phase-based approach which allowed to temporally dissect an Early, a Mid and a Late phase, each of which may differently reflect the decision conflict between automatic and controlled responses in the evolution of the mouse movement towards the target response. Our results show that the MT approach provides an accurate and finer-grained characterisation of the implicit racial attitude than classical RT-IAT. Finally, our novel phase-based approach can be an effective tool to shed light on the implicit conflict processing emerging in a categorisation task with a promising transferable value in different cognitive and neuropsychological fields.

Two Minds, One Patient: Clearing up Confusion About "Ambivalence"

Patients who experience difficulty making medical decisions are often referred to as "ambivalent." However, the current lack of attention to the nuances between a cluster of phenomena that resemble ambivalence means that we are not always recognizing what is really going on with a patient. Importantly, different kinds of "ambivalence" may call for different approaches. In this paper, we present a taxonomy of ambivalence-related phenomena, provide normative analysis of some of the effects of-and common responses to-such mental states, and sketch some practical strategies for addressing ambivalence. In applying lessons from the philosophical literature and decision theory, our aim is to provide ethicists and clinicians with the tools to better understand and effectively intervene in cases of ambivalence.

Taking Stock and Moving Forward: A Personalized Perspective on Mixed Emotions

Research on mixed emotions is flourishing but fractured. Several psychological subfields are working in parallel and separately from other disciplines also studying mixed emotions, which has led to a disorganized literature. In this article, we provide an overview of the literature on mixed emotions and discuss factors contributing to the lack of integration within and between fields. We present an organizing framework for the literature of mixed emotions on the basis of two distinct goals: solving the bipolar-bivariate debate and understanding the subjective experience of mixed emotions. We also present a personalized perspective that can be used when studying the subjective experience of mixed emotions. We emphasize the importance of assessing both state and trait emotions (e.g., momentary emotions, general levels of affect) alongside state and trait context (e.g., physical location, culture). We discuss three methodological approaches that we believe will be valuable in building a new mixed-emotions literature-inductive research methods, idiographic models of emotional experiences, and empirical assessment of emotion-eliciting contexts. We include recommendations throughout on applying these methods to research on mixed emotions, and we conclude with avenues for future interdisciplinary research. We hope that this perspective will foster research that results in the organized accumulation of knowledge about mixed emotions.

Two sides of the same leader: an agent-based model to analyze the effect of ambivalent opinion leaders in social networks

Opinion leaders (OLs) are becoming increasingly relevant on social networking sites as their visibility can help to shape their followers' attitudes toward a variety of issues. While earlier research provided initial evidence on the effect of OLs using agent-based modeling, it remains unclear how OLs affect their network environment and, therefore, the opinion climate when: (a) they publicly hold ambivalent attitudes, and (b) they not only express support for their own stance but also discredit or 'debunk' the opposing side. This paper presents an agent-based model that determines the influence of OLs in social networks in relation to ambivalence and discreditation. The model draws on theoretical foundations of OLs as well as attitudinal ambivalence and was implemented using two network topologies. Results indicate that OLs have significant influence on the opinion climate and that an unequal number of OLs of different opinion camps lead to an imbalance in the opinion climate only in certain situations. Furthermore, OLs can dominate the opinion climate and turn their stance into a majority opinion more effectively when discrediting the opposing side. Ambivalent OLs, on the other hand, can contribute to greater balance in the opinion climate. These findings provide a more nuanced analysis of OLs in social networks by pointing to potential amplifications as well as boundaries of their influence. Implications are discussed with a focus on human and artificial key actors in online networks and their efficacy therein.

Specificity in the Study of Mixed Emotions: A Theoretical Framework

Research on mixed emotions is yet to consider emotion-specificity, the idea that same-valenced emotions have distinctive characteristics and functions. We review two decades of research on mixed emotions, focusing on evidence for the occurrence of mixed emotions and the effects of mixed emotions on downstream outcomes. We then propose a novel theoretical framework of mixed-emotion-specificity with three foundational tenets: (a) Mixed emotions are distinguishable from single-valenced emotions and other mixed emotions based on their emotion-appraisal relationships; (b) Mixed emotions can further be characterized by four patterns that describe relationships between simultaneous appraisals or appraisals that are unique to mixed emotions; and (c) Carryover effects occur only on outcomes that are associated with the appraisal characteristics of mixed emotion. We outline how mixed-emotion-specific effects can be predicted based on the appraisal tendency framework. Temporal dynamics, the application of mixed-emotion-specificity to individual difference research, methodological issues, and future directions are also discussed.

Cognitive miserliness in argument literacy? Effects of intuitive and analytic thinking on recognizing fallacies

Fallacies are a particular type of informal argument that are psychologically compelling and often used for rhetorical purposes. Fallacies are unreasonable because the reasons they provide for their claims are irrelevant or insufficient. Ability to recognize the weakness of fallacies is part of what we call argument literacy and imporatant in rational thinking. Here we examine classic fallacies of types found in textbooks. In an experiment, participants evaluated the quality of fallacies and reasonable arguments. We instructed participants to think either intuitively, using their first impressions, or analytically, using rational deliberation. We analyzed responses, response times, and cursor trajectories (captured using mouse tracking). The results indicate that instructions to think analytically made people spend more time on the task but did not make them change their minds more often. When participants made errors, they were drawn towards the correct response, while responding correctly was more straightforward. The results are compatible with “smart intuition” accounts of dual-process theories of reasoning, rather than with corrective default-interventionist accounts. The findings are discussed in relation to whether theories developed to account for formal reasoning can help to explain the processing of everyday arguments.

Examining the mediating effect of psychosocial resources on the relationship between ambivalent feelings and depression among Israeli Arab family caregivers of people with dementia

Objectives

Providing care for family members of individuals with dementia can be accompanied by a myriad of emotions, usually involving negative as well as positive feelings, or “ambivalent feelings.” Recent studies conducted among family caregivers of people with dementia have shown ambivalent feelings to be associated with serious psychological consequences, such as increased depression. However, little is known about the path leading from ambivalent feelings to depression. Thus, the aim of this study was to examine the interplay of ambivalent feelings and depression with family caregivers’ psychosocial resources—that is, their coping strategies and social support.

Methods

A cross-sectional study using face-to-face interviews (via structured questionnaire) was conducted with 175 Israeli Arab family caregivers (adult children and spouses) of elderly people with Alzheimer’s disease (87.4% female; 72% adult children; mean age = 54.28).

Results

Overall, the participants reported a mild level of depression (mean = 7.93; SD = 4.30; range 0–15) and a moderate level of ambivalent feelings (mean = 1.63; SD = 1.04; range 0–3). Additionally, as expected, ambivalent feelings made a unique—although modest—contribution, adding an additional 6% ( p < 0.001) to the explanation of depression ( R2 = 0.56, p<0.001). Whereas, neither problem-focused coping nor emotion-focused coping played a significant role in mediating the relationship between ambivalent feelings and depression, social support did mediate the relationship between these variables.

Conclusions

Our findings show that strengthening and expanding social networks among Israeli caregivers of people with Alzheimer’s disease can minimize the impact of experiences of emotional feelings on depression.

Ambivalence and Self-Reported Adherence to Recommendations to Reduce the Spread of COVID-19

Abstract. Governments worldwide still, to some extent, rely on behavioral recommendations to reduce the spread of COVID-19. We examine the role of ambivalence toward both the specific recommendations (micro-ambivalence) and the pandemic as a whole (macro-ambivalence) about compliance. We predict that micro ambivalence relates negatively, whereas macro ambivalence relates positively to self-reported adherence to recommendations. We present two studies ( N = 691) supporting our hypotheses: the more ambivalent people are toward the behavioral recommendations (micro-level), the less they report following them. Conversely, the more ambivalent people are about the pandemic as a whole (macro-level), the more they report following recommendations. Our findings were replicated in a US sample and a representative German sample.

Thematic Co-occurrence Analysis: Advancing a Theory and Qualitative Method to Illuminate Ambivalent Experiences

Ambivalence is a phenomenon that transcends disciplinary divides and is associated with a myriad of mixed outcomes. Yet, identifying and representing the complexities of ambivalent experiences can be difficult using traditional qualitative methods. Thus, the goal of the present study was to advance a qualitative method, thematic co-occurrence analysis, to address this issue. To illustrate the usefulness of this method, I present a case study detailing 35 estranged adult children's ambivalent responses and reactions to their parents' (non)contact during the COVID-19 pandemic. Findings reveal seven themes and four (non)relationships between them that reflect (a) theme independence, (b) unilateral co-occurrence, (c) unbalanced co-occurrence, and (d) complementary co-occurrence. These findings advance a theory of ambivalence and corresponding method to aid in the future investigations of ambivalent phenomena.

The Arabic and Hebrew versions of the caregiving ambivalence scale (CAS): examining its reliability, validity, and correlates among Israeli caregivers of individuals with Alzheimer's disease

Objectives: Providing care for family members with Alzheimer's disease (AD) might awaken ambivalent feelings in caregivers. This topic, however, has received little research attention. Having reliable and valid scales is a first step in expanding our knowledge in this area, particularly among different cultural groups, as ambivalent emotions have been found to be dependent on culture. Thus, the aims of this study were (1) to test the reliability and validity of the Caregiving Ambivalence Scale (CAS) among Israeli Jewish and Arab caregivers of individuals with AD and (2) to examine the contribution of caregivers' ethnocultural affiliation (Jewish/Arab) to the experience of ambivalent feelings.Methods: Structured face-to-face interviews were conducted with 370 family caregivers (adult children and spouses) of elderly people with AD. Approximately half of the participants (55.3%) were Israeli Jews (79.5% female; 61.3% adult children; mean age = 65.52), and the rest (44.7%) were Israeli Arabs (87.4% female; 72% adult children; mean age = 54.28).Results: Our findings indicated that the CAS has good-to-excellent internal reliability and validity both in Hebrew and Arabic. Additionally, as expected, ethnocultural affiliation (Jewish/Arab) made a unique - although modest - contribution to the explanation of ambivalence as reflected in the CAS score, with Arab caregivers reporting significantly higher levels of ambivalent feelings than did Jewish caregivers.Conclusions: The CAS is a reliable and valid structured measure to assess ambivalent feelings among Arab and Jewish caregivers of individuals with AD in Israel. Cultural context is a unique factor in understanding their mixed emotions.

Are political-opinion pollsters missing ambivalence: "I love Trump"… "I hate Trump"

Given the increasing attention ambivalence is receiving from the psychological community, it must be asked if pollsters’ (routinely) dichotomous political opinion surveys are missing something crucial. To determine if there is any legitimacy to this question, undergraduates attending a Liberal Arts college in Southern California were asked to rate their level of agreement/disagreement to 28 statements regarding President Trump in two studies, with the items drawn from actual Quinnipiac (Q) and Brookings Institute (BI) surveys. To quantify ambivalence participants were told they could mark one or two responses per item, with double-responses serving as a measure of ambivalence. In Study 1, mean Trump approval ratings divided along party lines, and were consistent with the Q and BI findings. Nonetheless, approximately 40% of participants registered some level of ambivalence across all political-party affiliations, with those defining themselves as Neither Democrats (DEMs) nor Republicans (REPs) showing the greatest degree of ambivalence. In Study 2, ambivalence towards President Trump was examined looking at both party affiliation and political ideology (Conservative, Moderate, and Liberal). Again, roughly 40% of participants displayed some level of ambivalence, with greater degrees of ambivalence for Independents relative to DEMs and REPs, and Moderates relative to Liberals. Given research indicating that ambivalence is associated with delayed decision making and decisions based on “in the moment” contextual information, our findings our suggestive: if political opinion pollsters do not assess ambivalence, they may be missing information on a fair-sized demographic that could influence an election based on negative information (real or fictitious) surfacing only days before an election… as it did in 2016.

Predictors of Women's Awareness of the Benefits and Harms of Mammography Screening and Associations with Confusion, Ambivalence, and Information Seeking

In recent years, there has been a shift toward promoting informed decision making for mammography screening for average-risk women in their 40s. Professional organizations such as the American Cancer Society and U.S. Preventive Services Task Force recommend that women weigh the potential benefits and harms of mammography prior to initiating screening. This decision-making process assumes that women are aware of both the benefits and harms of screening, yet little is known about the prevalence and antecedents of such awareness. Moreover, it is conceivable that women who are aware of both the benefits and harms may interpret this information as conflicting - which could be concerning, as researchers have documented adverse effects of exposure to conflicting health information in prior research. Using data from a population-based survey of U.S. women aged 30-59 (N = 557), the current study found that awareness of mammography's harms is relatively low compared to awareness of benefits. Health news exposure and interpersonal communication about health were associated with greater awareness of harms. In addition, women's awareness of both the benefits and harms was positively associated with confusion about breast cancer screening recommendations, ambivalence about getting a mammogram, and mammogram-related information seeking from online sources. Implications for cancer screening communication are discussed.

Let's not be indifferent about robots: Neutral ratings on bipolar measures mask ambivalence in attitudes towards robots

Ambivalence, the simultaneous experience of both positive and negative feelings about one and the same attitude object, has been investigated within psychological attitude research for decades. Ambivalence is interpreted as an attitudinal conflict with distinct affective, behavioral, and cognitive consequences. In social psychological research, it has been shown that ambivalence is sometimes confused with neutrality due to the use of measures that cannot distinguish between neutrality and ambivalence. Likewise, in social robotics research the attitudes of users are often characterized as neutral. We assume that this is due to the fact that existing research regarding attitudes towards robots lacks the opportunity to measure ambivalence. In the current experiment (N = 45), we show that a neutral and a robot stimulus were evaluated equivalently when using a bipolar item, but evaluations differed greatly regarding self-reported ambivalence and arousal. This points to attitudes towards robots being in fact highly ambivalent, although they might appear neutral depending on the measurement method. To gain valid insights into people’s attitudes towards robots, positive and negative evaluations of robots should be measured separately, providing participants with measures to express evaluative conflict instead of administering bipolar items. Acknowledging the role of ambivalence in attitude research focusing on robots has the potential to deepen our understanding of users’ attitudes and their potential evaluative conflicts, and thus improve predictions of behavior from attitudes towards robots.

Bipolar or Independent? Relations Between Positive and Negative Affect Vary by Emotional Intelligence

Individuals who are intelligent concerning their emotions should experience them differently. In particular, being conversant with the valence dimension that is key to emotions should reasonably result in emotional experiences that are more bipolar with respect to this dimension. Pursuant of these ideas, three studies (total N = 335) assessed emotional intelligence in ability-related terms (ability EI). The same participants also reported on their recent experiences of positive affect (PA) and negative affect (NA) at work (studies 1 and 2) and/or their day-to-day emotional experiences within a daily diary protocol (study 3). Within each of these studies, ability EI moderated the relationship between experiences of PA and NA, such that the PA-NA relationship was more bipolar at higher levels of EI. These findings are discussed with respect to their implications for debates about bipolarity as well as for their value in highlighting ways in which the ability EI dimension operates.

Benefits of being ambivalent: The relationship between trait ambivalence and attribution biases

Ambivalence refers to the experience of having both positive and negative thoughts and feelings at the same time about the same object, person, or issue. Although ambivalence research has focused extensively on negative consequences, recently, scholars turned their lens to the positive effects of ambivalence, demonstrating beneficial effects on judgements and decision-making processes. So far, this work has focused on state ambivalence, which is ambivalence as a direct response to a specific stimulus. However, there are substantial individual differences in ambivalence: Some people are just more ambivalent than others. Taking a first step in understanding how these individual differences relate to judgement and decision-making, we examine the relationship between trait ambivalence and cognitive bias in social judgements tasks. Specifically, we look at two of the most pervasive and consequential attribution biases in person perception: correspondence bias and self-serving bias. We find a negative relationship between trait ambivalence and correspondence bias. The higher individuals are in trait ambivalence, the smaller their bias towards attributing behaviour to a person's disposition (Study 1A and B). We find the same for self-serving bias (Study 2A and B). In sum, we show that trait ambivalence is negatively related to cognitive bias in person perception.

Bittersweet: The Neuroscience of Ambivalent Affect

Ambivalent affective states, such as bittersweetness, nostalgia, and longing, which are felt as having both positive and negative aspects, are an important component of human experience but have received little attention. The most influential theoretical frameworks in affective neuroscience focus largely on univalenced states. As a result, it is not known whether ambivalent affect corresponds to a simultaneously positive and negative valenced state or whether it results from a rapid vacillation between positive and negative states. Here we hypothesize that ambivalent affect involves both mechanisms, that is, rapid vacillation and simultaneity of positive and negative affect, albeit at different neurobiological levels. Rapidly vacillating univalent emotions could give rise to an ambivalent feeling, a mechanism that depends on brainstem nuclei that facilitate rapid action programs of emotional behavior while inhibiting opposing behaviors. This reciprocal inhibition prevents organisms from simultaneously implementing responses to conflicting emotions but also allows for rapid switching between emotions triggered by counterfactual thinking and rapid reappraisal of situations. We propose that as these transitions occur and respective interoceptive information reaches the insular cortex, further processing of this "emotional moment" would allow separate emotional events to be experienced as one "mixed" and integrated feeling.

When in Doubt, Follow the Crowd? Responsiveness to Social Proof Nudges in the Absence of Clear Preferences

Nudges have gained popularity as a behavioral change tool that aims to facilitate the selection of the sensible choice option by altering the way choice options are presented. Although nudges are designed to facilitate these choices without interfering with people’s prior preferences, both the relation between individuals’ prior preferences and nudge effectiveness, as well as the notion that nudges ‘facilitate’ decision-making have received little empirical scrutiny. Two studies examine the hypothesis that a social proof nudge is particularly effective when people have no clear prior preference, either because people are indifferent (in a color-categorization task; Study 1, N = 255) or because people experience a choice conflict (making shopping decisions about meat products; Study 2, N = 97). Both studies employed a social proof nudge to steer participants’ choices. The potential facilitating effect of the nudge was tested using a mouse-tracker paradigm that implicitly assessed experienced uncertainty during decision-making. Results showed that the nudge was effective in steering participants’ decisions; the facilitation effect (i.e., reduced uncertainty regarding the decision) was only observed for conflicting preferences, but not under indifference. A better understanding of when and how nudges can influence individuals’ behavior may help in deciding whether nudges are an appropriate policy tool for changing particular undesirable behavior.

Selective invalidation of ambivalent pro-marijuana attitude components

INTRODUCTION

Attitudes of drug-abstinent youth considering marijuana initiation can be highly ambivalent. Invalidating pro-usage elements (i.e., opinions) of ambivalent marijuana attitudes, while leaving anti-marijuana elements intact, may create stronger, less ambivalent marijuana-resistant attitudes and lower usage intentions, while concurrently elucidating the role of ambivalence in persuasive prevention.

METHOD

From an initial pool of marijuana-abstinent middle-school students (N = 538), the quintile expressing the most negative attitudes toward a marijuana prevention appeal (N = 101) were randomly assigned to one of three conditions designed to invalidate pro-marijuana opinions. Analyses then tested their susceptibility to a second marijuana prevention appeal.

RESULTS

Personally threatening messages were found ineffective, but appeals contesting resistant responses significantly decreased ambivalence (p < .01). Mediational analyses showed that this decreased ambivalence was associated with less favorable attitudes and lower marijuana usage intentions (both p < .001). An attribution-based manipulation increased ambivalence (p < .05), which was associated with positive usage intentions mediated through positive attitudes (both p < .001).

CONCLUSION

Analyses elucidated the role of attitude ambivalence in prevention, providing a more complete understanding of potential facilitative use of ambivalence in prevention models based on prevention. Results support the further examination and use of methods that invalidate pro-marijuana opinions, thereby leading to greater susceptibility to subsequent prevention appeals.

Challenge and Threat: A Critical Review of the Literature and an Alternative Conceptualization

In this article, the authors describe a new theory, the Evaluative Space Approach to Challenge and Threat (ESACT). Prompted by the Biopsychosocial model of challenge and threat (BPS: Blascovich and Tomaka, 1996) and the development of the Theory of Challenge and Threat States in Athletes (Jones et al., 2009), recent years have witnessed a considerable increase in research examining challenge and threat in sport. This manuscript provides a critical review of the literature examining challenge and threat in sport, tracing its historical development and some of the current empirical ambiguities. To reconcile some of these ambiguities, and utilizing neurobiological evidence associated with approach and avoidance motivation (c.f. Elliot and Covington, 2001), this paper draws upon the Evaluative Space Model (ESM; Cacioppo et al., 1997) and considers the implications for understanding challenge and threat in sport. For example, rather than see challenge and threat as opposite ends of a single bipolar continuum, the ESM implies that individuals could be (1) challenged, (2) threatened, (3) challenged and threatened, or (4) neither challenged or threatened by a particular stimulus. From this perspective, it could be argued that the appraisal of some sport situations as both challenging and threatening could be advantageous, whereas the current literature seems to imply that the appraisal of stress as a threat is maladaptive for performance. The ESACT provides several testable hypotheses for advancing understanding of challenge and threat (in sport) and we describe a number of measures that can be used to examine these hypotheses. In sum, this paper provides a significant theoretical, empirical, and practical contribution to our understanding of challenge and threat (in sport).

Does art expertise facilitate distancing?

With respect to the Distancing-Embracing model, we discuss whether experts with well-developed and highly accessible schemata that lend themselves to distancing have initial affective reactions similar to those of novices, who lack access to well-developed distancing mechanisms, and whether differences between experts' and novices' responses are apparent only after distancing mechanisms have had a chance to do their work. We revisit findings from Leder et al. (2014) and discuss the role of mixed emotions and fluency.

Semantic and affective manifestations of ambi (valence)

People sometimes report both pleasant and unpleasant feelings when presented with affective stimuli. However, what is reported as "mixed emotions" might reflect semantic knowledge about the stimulus (Russell, J. A. (2017). Mixed emotions viewed from the psychological constructionist perspective. Emotion Review, 9(2), 111-117). The following research examines to what degree self-reported mixed emotions represent actual feelings compared to knowledge about the stimulus. In a series of three experiments, participants reported either their feelings or their knowledge in response to affective stimuli. In Experiment 1, we sampled the entire IAPS pictorial space and examined the proportion of mixed emotion ratings using feelings-focused and knowledge-focused self-reports. We found a higher degree of mixed emotions under knowledge-focused than feelings-focused self-reports. In Experiment 2, we used a priori selected pictures to elicit mixed emotions. The proportion of mixed emotions was again higher under knowledge-focused instructions. In Experiment 3, we used movie clips that were previously used to elicit mixed emotions. In contrast to Experiments 1 and 2, there was no difference between feelings-focused and knowledge-focused self-reports. The results suggest a strong semantic component and a weak experiential component of self-reports in the case of pictorial stimuli. However, ambivalent movie clips elicited a stronger experiential component, thus supporting the existence of mixed emotions at the level of feelings.

Doing psychological science by hand

Over the past decade, mouse-tracking in choice tasks has become a popular method across psychological science. This method exploits hand movements as a measure of multiple response activations that can be tracked continuously over hundreds of milliseconds. Whereas early mouse-tracking research focused on specific debates, researchers have realized the methodology has far broader theoretical value. This more recent work demonstrates that mouse-tracking is a widely applicable measure across the field, capable of exposing the micro-structure of real-time decisions including their component processes and millisecond-resolution time-course in ways that inform theory. In the article, recent advances in the mouse-tracking approach are described, and comparisons with the gold standard measure of reaction time and other temporally-sensitive methodologies are provided. Future directions, including mapping to neural representations with brain-imaging and ways to improve our theoretical understanding of mouse-tracking methodology, are discussed.

Ambivalence: A Key to Clinical Trial Participation?

Trust exerts a multidimensional influence at the interpersonal level in the clinical trials setting. Trust and distrust are dynamic states that are impacted, either positively or negatively, with each participant-clinical trials team interaction. Currently, accepted models of trust posit that trust and distrust coexist and their effects on engagement and retention in clinical trials are mediated by ambivalence. While understanding of trust has been informed by a robust body of work, the role of distrust and ambivalence in the trust building process are less well understood. Furthermore, the role of ambivalence and its relationship to trust and distrust in the clinical trials and oncology settings are not known. Ambivalence is a normal and uncomfortable state in the complex decision making process that characterizes the recruitment and active treatment phases of the clinical trials experience. The current review was conducted to understand the constructs of ambivalence as a mediator of trust and distrust among vulnerable, minority participants through different stages of the oncology clinical trials continuum, its triggers and the contextual factors that might influence it in the setting of minority participation in oncology clinical trials. In addition, the researchers have sought to link theory to clinical intervention by investigating the feasibility and role of Motivational Interviewing in different stages of the clinical trials continuum. Findings suggest that ambivalence can be processed and managed to enable a participant to generate a response to their ambivalence. Thus, recognizing and managing triggers of ambivalence, which include, contradictory goals, role conflicts, membership dualities, and supporting participants through the process of reducing ambivalence is critical to successfully managing trust. Contextual factors related to the totality of one's previous health-care experience, specifically among the marginalized or vulnerable, can contribute to interpersonal ambivalence. In addition, changes in information gathering as a moderator of interpersonal ambivalence may have enormous implications for gathering, assessing, and accepting health information. Finally, motivational Interviewing has widespread applications in healthcare settings, which includes enabling participants to navigate ambivalence in shared-decision making with their clinician, as well as executing changes in participant behavior. Ultimately, the Integrated Model of Trust can incorporate the role of therapeutic techniques like Motivational Interviewing in different stages of the clinical trials continuum. Ambivalence is a key component of clinical trial participation; like trust, ambivalence can be managed and plays a major role in the management of trust in interpersonal relationships over time. The management of ambivalence may play a major role in increasing clinical trial participation particularly among the marginalized or the vulnerable, who may be more susceptible to feelings of ambivalence.
